GMC Trucks Acadia Tires

GMC Trucks Acadia uses nine tire sizes across the 2007-2026 range: 255/65R18 for 2007-2016 and 2025-2026, 255/60R19 for 2007-2016, 255/55R20 for 2008 and 2010-2016 plus 2024-2026, 235/55R20 for 2017-2023, 245/65R17 for 2017-2021, 235/65R18 for 2017-2023, 255/65R17 for 2019-2023, 265/65R18 for 2024-2026, and 275/45R22 for 2024-2026. Those sizes correspond to 17-inch, 18-inch, 19-inch, 20-inch, and 22-inch wheel diameters depending on year and configuration.

The important point is that GMC Trucks Acadia does not have one correct size per year in many cases. Start with the door-jamb placard, the tire size on the vehicle, and the measured wheel diameter, then use the year range to confirm you are choosing from the right group rather than assuming all Acadia models in that year used the same tire.

GMC Trucks Acadia uses several rim diameters over its production span: 18-inch wheels at the beginning in 2007, 19-inch and 20-inch applications beginning in 2008, 17-inch applications beginning in 2017, and a 22-inch application beginning in 2024. The wheel diameter is the last number in each metric size code, so R17 means a 17-inch wheel, R18 means 18-inch, R19 means 19-inch, R20 means 20-inch, and R22 means 22-inch.

That wheel diameter is the first fitment check because tires cannot be mounted across different rim diameters. If a GMC Trucks Acadia falls in a year with several listed sizes, physically confirm the wheel diameter on the vehicle before comparing widths and aspect ratios.

A 2019 GMC Trucks Acadia can use 235/55R20, 235/65R18, 245/65R17, or 255/65R17 because that model year spans multiple wheel-package configurations. The split is a rim-diameter and package split, with 17-inch, 18-inch, and 20-inch applications all appearing in the same year rather than one universal 2019 size.

That means year alone is not enough to pick the correct tire for a 2019 GMC Trucks Acadia. Verify the wheel diameter first, then confirm whether the vehicle carries the narrower or wider 17-inch package before matching the exact size.

On a GMC Trucks Acadia, 255/60R19 is a modern metric radial size. The 255 is the section width in millimeters, 60 is the aspect ratio showing the sidewall height as 60 percent of the width, R identifies radial construction, and 19 is the wheel diameter in inches. That size appears on 2007-2016 Acadia applications with 19-inch wheels.

Reading the code correctly helps separate sizes that may look similar at a glance, such as 255/65R18 and 255/55R20. A change in the last number always means a different wheel diameter, so the code should be matched to the wheel before any other comparison.

A 2017 GMC Trucks Acadia can use 245/65R17, 235/65R18, or 235/55R20, so the correct choice depends on the wheel package fitted to that specific vehicle. The 17-inch option is different not only in width and aspect ratio, but also in wheel diameter from the 18-inch and 20-inch alternatives listed for the same year.

Check the tire placard, read the full size from the tire currently mounted if it matches the vehicle, and confirm the wheel diameter directly. Using all three checks together is the best way to separate a genuine 17-inch application from an 18-inch or 20-inch GMC Trucks Acadia in the same model year.

The current GMC Trucks Acadia products listed here use an RWL sidewall, meaning raised white letters. That sidewall style appears on the available BFGoodrich all-terrain radials in 245/65R17 and 255/65R17.

Raised white letters give a more aggressive truck-oriented appearance than a plain black sidewall, which may suit some GMC Trucks Acadia owners and not others. If appearance matters as much as size, compare the sidewall style with the look you want before choosing between the available 17-inch products.

The currently listed GMC Trucks Acadia products are from BFGoodrich. The available covered sizes are 245/65R17 and 255/65R17, both in the All-Terrain T/A KO2 line.

That means the current product selection is concentrated around later 17-inch Acadia applications rather than the full range of sizes used across every year. If your GMC Trucks Acadia uses an 18-inch, 19-inch, 20-inch, or 22-inch package, confirm size first and then compare against the year listing before narrowing down product choices.

The listed GMC Trucks Acadia products currently fall under one series: BFGoodrich All-Terrain T/A KO2. That is a radial all-terrain tire line, and both available Acadia products in this group use that same series rather than separate touring, vintage, or bias-ply constructions.

Because the available series is all-terrain in character, the main buying decision here is not between multiple construction families but whether your GMC Trucks Acadia actually uses one of the covered 17-inch sizes. Once size is confirmed, you can decide whether the all-terrain look and intended use align with how the vehicle is driven.

A GMC Trucks Acadia should be stored on a clean, dry surface away from direct sunlight, ozone sources, and major temperature swings. Tires last better when they are kept out of prolonged UV exposure and are not left supporting a vehicle with low inflation for long periods.

If a GMC Trucks Acadia sits for extended stretches, move it occasionally or use appropriate support methods to reduce flat spotting. Keeping the tires properly inflated for storage conditions and checking them before the next drive helps preserve both ride quality and casing condition.

Tires on a GMC Trucks Acadia should be inspected regularly, with a visual check before driving and a more thorough inspection at routine service intervals. Look for cracking, bulges, punctures, irregular shoulder wear, tread separation signs, and any mismatch between the tire size fitted and the wheel package expected for the vehicle.

Regular inspection matters even more on an Acadia that sees seasonal or low annual mileage, because age-related issues can appear before the tread looks worn out. Catching pressure loss, alignment wear, or impact damage early is the simplest way to avoid replacing a tire after a preventable failure.

Tires on a GMC Trucks Acadia should be replaced when they show structural cracking, repeated air loss, impact damage, bulges, uneven wear that cannot be corrected, or age-related deterioration even if the tread depth still looks usable. Tread alone is not the whole story on a vehicle that may spend periods parked and then return to service.

Aging collector habits can affect newer vehicles too, especially if a GMC Trucks Acadia is driven infrequently. If the tire casing, sidewall, or bead area shows deterioration, replacement is the prudent move before more road use rather than trying to stretch service life from tread remaining on the surface.

GMC Trucks Acadia was fitted with multiple tire sizes across its production run rather than one original tire specification for every year. Early models used combinations such as 255/65R18 and 255/60R19, later years introduced 17-inch, 18-inch, and 20-inch alternatives, and 2024-2026 added a 22-inch package.

For an accurate restoration or factory-correct presentation, match the tire size to the exact year and wheel package on the vehicle rather than the model name alone. Original window stickers, service labels, and marque-specific reference material are the best tools for confirming what a particular GMC Trucks Acadia carried when new.

Correct tire fitment can affect how a GMC Trucks Acadia is judged, presented, and valued, especially when the vehicle is being kept close to factory appearance. A visible mismatch in wheel diameter, sidewall profile, or overall stance can change the look of the vehicle even when the tire physically fits the wheel.

That matters most on clean, well-preserved examples where details separate an accurate presentation from a merely usable one. If the goal is authenticity, verify the exact year-specific size and wheel package first, then consider whether a more aggressive replacement style matches the way you want the Acadia to be seen.

The currently listed GMC Trucks Acadia products use RWL, or raised white letters. That sidewall style is associated here with the available BFGoodrich all-terrain 17-inch options rather than a broad range of factory-style sidewall treatments across every Acadia year.

For a restoration-minded GMC Trucks Acadia owner, sidewall style should match the appearance goal as closely as the size does. If the aim is a stock look, compare the visual character of raised white letters to the original presentation of the vehicle before fitting an all-terrain style simply because the size is available.

A tire for a GMC Trucks Acadia can be suitable for public-road use when the size, load capacity, speed rating, wheel diameter, and overall condition all match the application. The currently listed Acadia products are modern radial tires in 17-inch sizes, with load capacities of 2,405 pounds at 65 psi for 245/65R17 and 2,600 pounds at 65 psi for 255/65R17.

Safety comes from correct fitment and condition, not from size designation alone. Before road use, make sure the GMC Trucks Acadia is on the correct wheel diameter and that the tires are free from age damage, impact damage, and abnormal wear.

Before driving a GMC Trucks Acadia, check inflation pressure, tread and sidewall condition, visible damage, and the exact tire size on the vehicle. On this model especially, confirm that the wheel diameter and tire size match one another because Acadia applications span 17-inch through 22-inch packages depending on year and configuration.

A quick walk-around can catch the most common problems: a low tire, a damaged sidewall, or a mismatch after a wheel swap. That simple check is particularly important on used or newly acquired GMC Trucks Acadia models, where the installed wheel package may not be the one the vehicle left the factory with.

Appropriate speed for a GMC Trucks Acadia depends on the exact tire fitted, its speed rating, its condition, and whether the vehicle remains on the intended wheel-and-tire combination. For example, the listed 245/65R17 and 255/65R17 products carry an S speed rating, but that should never override the limits created by age, wear, inflation, or mechanical condition.

The practical rule is to drive within the capability of the actual tire on the vehicle, not just the model name or the speed limit posted on the road. If a GMC Trucks Acadia has older tires, uneven wear, or an unverified wheel-package change, conservative speeds are the wiser choice until the setup is fully checked.
